STEERING WORM AND

SECTOR

GEAR ADJUSTMENTS

The ball nut assembly and the sec-

tor gear must be adjusted properly to

maintain minimum steering shaft end

play (a factor of preload adjustment)

and minimum backlash between sector

gear and ball nut. There are only two

possible adjustments within the recir-

culating ball-type steering gear, and

these should be made in the following

order to avoid damage or gear failure.

1.
Disconnect the Pitman arm from

the steering Pitman-to-idler arm rod.

2.
Loosen the nut which locks the

sector adjusting screw (Fig. 3), and

turn the adjusting screw counterclock-

wise.
(On models equipped with the

Cobra Jet engine, it may be necessary

to use a suitable holding tool with an

extension and a long screwdriver to

make the gear adjustment).

3.
Measure the worm bearing pre-

load by attaching an in-lb torque

wrench to the steering wheel nut (Fig.

4).
With the steering wheel off center,

read the pull required to rotate the

input shaft approximately 1 1/2 turns

either side of center. If the torque or

preload is not within specification

(Part 3-1), adjust as explained in the

next step.

MAJOR REPAIR OPERATIONS

In most cases, complete disassembly

of the power steering gear will not be

necessary. It is suggested that only

those assemblies that are faulty be dis-

assembled. Disassembly and reassem-

bly of the unit and the subassemblies

must be made on a clean workbench.

As in repairing any hydraulically op-

erated unit, cleanliness is of utmost

importance. Therefore, the bench,
tools,
and parts must be kept clean at

all times. Thoroughly clean the exter-

ior of the unit with a suitable solvent

and when necessary, drain as much of

the hydraulic oil as possible. Handle

all parts very carefully to avoid nicks,

burrs,
scratches and dirt, which could

make the parts unfit for use. Do not

clean, wash or soak seals in cleaning

solvent.
VALVE CENTERING

SHIM REPLACEMENT

The pattern taken during disassem-

bly should be helpful in judging if

gears can be re-used. Worn gears can-

not be rebuilt to correct a noisy condi-

tion. Gear scoring is the result of ex-

cessive shock loading or the use of an

incorrect lubricant. Scored gears can-

not be re-used.

Examine the teeth and thrust surfa-

ces of the differential gears. Wear on

the hub of the differential gear can

cause a chucking noise known as

chuckle when the vehicle is driven at

low speeds. Wear of splines, thrust

surfaces, or thrust washers, can con-

tribute to excessive drive line back-

lash.

BEARING CUPS AND

CONE AND ROLLER

ASSEMBLIES

Check bearing cups for rings,

scores, galling, or excessively worn

wear patterns. Pinion cups must be

solidly seated. Check by attempting to

insert a 0.0015-inch feeler between

these cups and the bottoms of their

bores.

When operated in the cups, cone

and roller assemblies must turn with-

out roughness. Examine the roller

ends for wear. Step-wear on the roller

ends indicates the bearings were not

preloaded properly, or the rollers were

slightly misaligned.

If inspection reveals either a defec-

tive cup or a defective cone and roller

assembly, both parts should be re-

placed to avoid early failure.

DIFFERENTIAL BEARING

ADJUSTING NUTS

Temporarily install the bearing caps

and test the fit of the adjusting nuts in

their threads. The nuts should turn

easily when the caps are tightened to

25 ft-lbs. The faces of the nuts that

contact the bearing cups must be

smooth and square. Replace the nuts

or examine the threads in the carrier
if their fit is not proper. Be sure that

the bearing caps and adjusting nuts

are on the side they were machined to

fit. Observe the punch marks and

scribe marks made during disassem-

bly.

U-JOINT FLANGE

Be sure that the eai» of the flange

have not been damaged in removing

the drive shaft or in removing the

flange from the axle. The end of the

flange that contacts the front pinion

bearing inner race as well as the flat

surface of the pinion nut counterbore

must be smooth. Polish these surfaces

if necessary. Roughness aggravates

backlash noises and causes wear of

the flange and pinion nut with a resul-

tant loss in pinion bearing preload.

PINION RETAINER

Be sure that the pinion bearing cups

are seated. Remove any chips or burrs

from the mounting flange. Clean the

groove for the O-ring seal and all lu-

bricant passages. If the cups were re-

moved, examine the bores carefully.

Any nicks or burrs in these bores

must be removed to permit proper

seating of the cups.

CARRIER HOUSING

Make sure that the differential

bearing bores are smooth and the

threads are not damaged. Remove any

nicks or burrs from the mounting sur-

faces of the carrier housing.

DIFFERENTIAL CASE

Make sure that the hubs where the

bearings mount are smooth. Carefully

examine the differential case bearing

shoulders, which may have been dam-

aged when the bearings were removed.

The bearing assemblies will fail if they

do not seat firmly against the shoul-

ders.
Check the fit (free rotation) of
the differential side gears in their

counterbores. Be sure that the mating

surfaces of the two parts of the case

are smooth and free from nicks or

burrs.

LIMITED SLIP AND

TRACTION-LOK

DIFFERENTIAL PARTS

Inspect the clutch plates for uneven

or extreme wear. The dog-eared clutch

plates must be free from burrs, nicks

or scratches which could cause excess-

ive or erratic wear to the bonding ma-

terial of the internally splined clutch

plates.
The internally splined clutch

plates should be inspected for condi-

tion of the bond, bonding material,

and wear. Replace the bonded plates

if their thickness is less than 0.085

inch or if the bonded material is

scored or badly worn. Inspect the

bonded plate internal teeth for wear.

Replace them, if excessive wear is evi-

dent. Bonded plates should be re-

placed as a set only

Examine all thrust surfaces and

hubs for wear. Abnormal wear on

these surfaces can contribute to a

noisy axle.

Inspect the Belleville spring (limited

slip) for proper free height of 1/4

inch.

LUBRICANT LEVEL

The lubricant level should be

checked every 6000 miles with the ve-

hicle in normal curb attitude. The lu-

bricant level should be at the lower

edge of the filler plug hole located in

either the carrier casting or housing

cover. It is unnecessary to periodically

drain the axle lubricant. The factory

fill should remain in the housing for

the life of the vehicle, except when re-

pairs are made. The specified lubri-

cant should be installed when the axle

is overhauled.procarmanuals.com

is,
it is supported by bearings both in

front of and to the rear of the pinion

gear. Two opposed tapered roller

bearings support the pinion shaft in

front of the pinion gear with a col-

lapsible spacer for 8-3/4 inch or 9

inch ring gear, and a solid spacer used

with the 9 3/8 inch ring gear. A

straight roller (pilot) bearing supports

the pinion shaft at the rear of the pi-

nion gear. Pinion and ring gear tooth

contact is adjusted by adding or re-

moving shims from between the pinion

retainer and the carrier housing.

The differential assembly is mount-

ed on two opposed tapered roller

bearings, which are retained in the

carrier by removable caps. The entire

carrier assembly is bolted to the axle

housing.

Ball bearing assemblies (rear wheel

bearings) are pressed onto the outer

ends of the axle shafts and set in the

outer ends of the axle housing. These

bearings support the semi-floating

axle shafts at the outer ends. The

inner ends of the shafts spline to the

differential side gears. Bearing retain-

er plates hold the shafts in the hous-

ing. The left and right axle shafts are

not interchangeable, the left shaft

being shorter than the right.

LIMITED-SUP DIFFERENTIAL

The axle assembly, except for the

differential case and its internal com-

ponents, is identical to the convention-

al axle.

A constant-friction locking differen-

tial,
which employs clutch plates to

control differential action, is available

as optional equipment (Fig. 2).

Four steel clutch plates are locked

into the differential cover. Three

bronze, bonded clutch plates are

splined to a clutch hub which, in turn,
is splined to the left axle shaft. A

Belleville spring washer maintains a

constant pressure between the steel

and bonded clutch plates so that the

clutch is always engaged.

TRACTION-LOK

DIFFERENTIAL

The Traction-Lok (torque sensitive)

locking differential (Fig. 3) employs a

multiple disc clutch to control differ-

ential action. Shim(s), which control

side gear mounting distance, four

steel, four friction and one composite

plate (steel on one side and friction

material on the other) stacked on a

clutch hub, and four ear guides are

housed in the differential cover. Lo-

cated in the differential case between

the side gears is a one-piece pre-load

plate and block (four-pinion) and four

calibrated pre-load springs, which

apply an initial force to the clutch

pack. Additional clutch capacity is

derived from the side gear thrust

loads.
The four friction plates are

splined to the clutch hub which in turn

is splined to the left axle shaft, and

the eared steel plates are dogged to

the case; thus, the clutch is always en-

gaged.
